MMA’s Great Debate Radio returns for Tuesday’s show with UFC on FX 8 headliner Luke Rockhold and former UFC champion Josh Barnett.

There are also all-new topics that include Bellator, drug testing in MMA, and Alistair Overeem’s UFC return.

The debate topics include:

• Bellator continues to take a hit in the media with new stories surrounding Eddie Alvarez, Leonard Garcia and Zach Makovsky. How damaging is this latest round of information to Bellator’s bottom line?

• Ben Askren has also stated since he’s been with Bellator he’s been drug tested just once. Is this a big problem or making a big deal out of nothing?

• Alistair Overeem will return at UFC 164 in Milwaukee. Do you believe he can still get to a title shot in the UFC or has that ship sailed?

• Josh Barnett wants to return to the UFC. How will the Warmaster do against the new crop of heavyweight talent?
